We are pleased to bring you these amazing interchangable v4 510 connectors from Fat Daddy Vapes. It comes as standard with a 15mm juice well which can be taken off from the outside of the mod and swapped with either a 22mm or a 30mm juice well.

This version has 2mm more thread than the v3 making it ideal for wooden mods or any mod that has a thicker enclosure.
All in all, an amazing piece of engineering that not only looks the part, but works flawlessly.
